INTRODUCTION
The requirement analysis is the success key factor for software development for an organization. Previously, the concentration has been at the configuration and code level instead of at the requirements level. This is because of the challenges in distinguishing conditions in a text -based requirement specifications which leads to miscommunication between the business analyst and business people causing failure of proposed change as the prerequisites are not addressed properly. Business Modelling Process is a best method to prevent these problems In this paper the analysis of role of Business Process Modelling Notation (BPMN) models in requirements dependency analysis. Mapping between workflow patterns and various dependency types is made to support dependency identification. A comparison is done shedding light on how more dependencies can be spotted using mapping then that of text based requirements which are helpful in change impact analysis with the support of a case study. Business models depict the structure and behaviour of an organization , and are very useful in helping developers properly understand the business environment and the requirements that an information system must fulfil.
Approach for Business Process Modelling Notation- Based Requirement Engineering
In requirements engineering Business process models (BPMs) are commonly used. Jose Luis de la Vara; Juan Sánchez provided a three stages model for driving requirements . Three steps of this model are as
• organizational modelling
• business process analysis
• Functional requirements specification.
At first stage, the a proper understanding of the business is made by interviewing the various employees working at different designations in ...

Found in the case study entitled, Promotion from Within at Citrus Glen, is a staffing process concern. The Citrus Glen Company, based in Florida, is a juice producer that supplies orange and grapefruit to food processors, grocery stores, convenience stores and restaurants in the United States. With rapid growth over the last few years, the HR vice president, Mandarine “Mandy” Pamplemousse, has been worried about how to staff the ever-expanding array of positions for Citrus Glen. Her concern is how to hire and promote enough individuals who are qualified for the needed positions. When Mandy is trying to staff internally, she uses a contractor based in Charlotte, NC called, Staffing Systems International (SSI). When positions become available that are appropriate to staff internally, she sends a group of candidates for the position to SSI to participate in the assessment center. The candidates are in the assessment process for three days. Mandy receives the results with recommendations, a few days after

Controlled Requirement Expression (CORE) was developed for the British Aerospace programs while the UK Ministry of Defence was carrying out a requirement analysis (Hull et al., 2010). The fundamental component of the CORE methodology is viewpoints as different users see systems in different ways. There are many different stakeholders involved in a system; using CORE methodology involves finding all the different viewpoints of those stakeholders that have an interest in the system whether it’s a person, role or organisation ext.… (Sommerville and Sawyer, 2000). By organising viewpoints hierarchy it assists experts to read the scope and supports the analysis process. CORE Methodology is extensively used for real time system requirements specification.
The paper presents a detailed discussion on implementation of BIM in a construction project by defining a BIM team in the various phases of construction i.e. from conception to commissioning. Also, the paper presents a brief discussion on processing the information utilizing the i-rooms.
This method also empowered the employees giving them an opportunity to increase their skill levels and an opportuni...
The major issues facing the company comprises of there being multiple businesses with different demands. There are separate levels of performance and success as well as growth chances for each of the sector and the firm needs to tackle with issues in each of these divisions (Dube, J.P., 2004).

Logical modeling deals with gathering system requirements and translating those requirements into a model. The logical model revolves around the requests of the business and system requirements. Logical modeling involves collecting information about business procedures, groups of data, and business units. After this information is assembled, diagrams and reports are produced including diagrams, business process diagrams, and eventually process flow diagrams. The diagrams created, should show the processes and data that exist, as well as t...
Way of Thinking – Unified Process is a predictive and adaptive approach of software development methodology based on object oriented principles. (Satzinger & Others, 2005) It is use case driven approach focused on developing the system incrementally by delivering the captured functional requirements in iterations. (So-Young & Ho-Jin, 2005) Creating different artifacts throughout the development process eliminates the possibility of undefined requirement and miscommunication. (Rational, 1998) Modularity embedded in the process allows developing and delivering of system in components. Maintaining software quality and requirement changes are integral part of process.

The Waterfall model is more or less totally linear in progression with six specific stages being undertaken in chronologically descending order. The first stage is known as the Requirements stage, in which the document of product requirements is created for future reference. The Design procedure is the second stage, which culminates in the architecture for the base software. Next, the Construction stage occurs, where the implementation of coding upon the base architecture results in the actual software being created. The fourth stage is Integration, where the software is made ready for the systems that it will become a part of, merging it to create the first step of the final product. Testing and debugging then occur to make sure that Integration worked as planned without the introduction of new errors due to the integration or that old mistakes do not take on a new potency due to the change in the software. Finally, Installation of the product occurs, finishing the product, which is taken up by the Software and the Maintenance steps of the six-stage Waterfall model. There are non-traditional variations of the waterfall method, but these are not relevant to the current discussion, and as such, will not be covered at this time.
The distinction between the start-up and growth stages in not easily defined. The distinction lies in the revenues, profits are stronger and are consistent with an increase in customers, as well as, new and exciting opportunities for the employees to pursue. Managers can look forward to many managerial challenges, perspective policy issues and re-evaluating the business plan for revisions. A manager’s focus should be in the running of the business, with a greater emphasis on accounting and human resource management systems. New staff will have to be hired, trained and prepared for the influx of business.
As part of developing the need in the initial investigation step in the systems development life cycles (SDLC) process, a constructive method is use case. Use case is a technique for capturing requirements with written scenarios in non-technical terminology that describe how a system interacts with a user or another system (University of Phoenix, Course Syllabus, 2006). There are two fundamental pieces, along with how they relate, to bear in mind: the actors and the goals. The actors are everyone and everything that will use (or be used) by the project progress reports, and the goals, which are what the actors want to achieve. The use case will describe the goals achieved by the actors who perform tasks (Carr & Meehan, 2005).
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also
Often every business plan starts with a process, a business process. A business process is a collection of related, structured activities or tasks that produces a specific service or product for a particular customer or customers. There are three different types of business process. Management process governs the operation of a system. Business Process Reengineering is the analysis and design of workflow and processes within an organization. A business process is a set of logically related tasks that are utilized to help achieved a more defined business success. Reengineering is actually the basis in many developments of management.
What's e-business? It is the transformation of every business process through using the internet and associated technologies. In this transformation, each part of the business becomes a part of an intrinsic network, which enables employees, suppliers and customers of a given enterprise to conduct their tasks. People usually try to make a point in differing e-business from e-commence, but as I see, e-commerce is a part of the e-business category, and an important one.
